Christ, MJ! That one was the size of a vacuum cleaner. I didn't so much step on it, as fall over it!I can see why you let it out to play, though. If a crab that size was hanging off one's muff 24/7, it'd play havoc with one's back.

FYI, shaving will not get rid of the crabs; using a lotion such as Derbac will get rid of the crabs. Don't forget to launder the sheets and clothes and towels and to notify all your partners to treat themselves to prevent reinfestation.
